Summary:
We can still not replicate this failure on test or production machines at Adobe. This appears to occur on Lightroom 12.4/Camera Raw 15.4 and later on very old Macs (8 Years and older) and is likely due to out-of-date video drivers on no longer-supported or updated GPUs.
The issue manifests as visual color artifacts in the Develop view only but doesn't always appear on exported images. It can also manifest as less-than-black deep shadow areas.

I’ve got an issue with Lightroom that I can't seem to resolve. I'll be using Lightroom with no issues, then all of a sudden all the blacks that are clipped will start showing up as clipped. Only problem is, I don't have that setting selected. If I hit 'J' the clipping marks don't go away. If I export the images the clipping marks are there. If I restart Lightroom and export the clipping marks are there.
I can get the marks to go away by restarting Lightroom, but I'm going mad constantly restarting. Sometimes the problem will happen immediately again and sometimes it won't happen again for 24 hours or so. Here is an exaple of what an exported image looks like when the marks are there.
I'm a professional photographer so I'm no stranger to Lightroom, but I can't seem to resolve this problem. Someone please help save my sanity!
I do not trust till now the new release 13.1., because it is not clear for me, whether this subject is solved or not. Would be godd, to get a clear statement.
Thx and greeting

The release notes for 13.1 say that the issue "Image Export always uses GPU even when the preference is unset" is resolved:

There is no other way until Adobe provides a workaround for the bug apparently present in the drivers for the GPU cards in these older macs. The drivers are never going to be updated (machines and GPUs are too old) so only way is if Adobe finds a workaround for the driver bugs that works with the new code introduced for the v6 process version. Barring that only feasible fix might be for Adobe to competely disable the GPU for these machines which would make Lightroom really slow or they might simply declare Lightroom incompatible with these machines. Not sure if this will ever get fixed therefore but hopefully Adobe surprises us.

Wrong focus. Please ignore speculation about whether it's an issue with old drivers having bugs. Lr Classic 12.3 can use the GPU without a problem. Lr Classic 12.4 cannot. I.e. this is a bug that Adobe introduced. They can choose to debug/bisect their code and find what they did to cause the problem, or, as you suggest, they can choose to disable GPU support or the feature of GPU support that causes the problem on these devices.
Adobe can fix things quickly if they want to. This discussion has been going on for half a year, so clearly Adobe have decided not to prioritise it. They've tried to cut off people on older systems in Lr Classic 13 by requiring macOS versions that were only released in the last couple of years, but that's hasn't worked. It's amazing how many people continue to popup with this problem, but maybe in the grand scheme of things these are small numbers and somebody at Adobe has decided they're not worth spending money/time on and it won't sufficiently hurt their profits, reputation or shareholder value, or the risk of a law suit is too low. Meanwhile, they're continuing to take a monthly fee from people and giving nothing back. It's criminal, and they should either fix this or convert people on old versions that they won't fix to permanent licenses instead of continuing to take their money.
The arrogance and indifference shown by Adobe in relation to this problem is remarkable.

Perhaps even contempt towards their users? We're just here to provide money for their shareholders.
